FYA

I cannot write this biography as requested. The facts provided describe "Fya" as a song by BTS, not as an artist or group. The instruction asks for an artist biography for "Fya" as a musical entity, but the only information given identifies it as a single track rather than an independent artist.

To write an accurate biography following your critical instruction to use only provided facts, I would need information about Fya as an artist—their formation, background, or career—rather than data about a BTS song.
